The tower consists of discontinuous lateral resistant members and plane size setback along the height. Performance-based seismic design was adopted when critical parts and weak parts were carried out elastic analysis under the moderate earthquake and non-yielding analysis under the rare earthquake. Strengthening measures were adopted to ensure seismic requirements of “not collapse under the rare earthquake”.Keywords: complex high-rise building; performance-based seismic design; conversion truss; vertical size changes作者簡(jiǎn)介：馮銘，碩士，高級(jí)工程師，Email：kgjtycw@126.com。參考文獻(xiàn)［1］JGJ 3—2010高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程［S］.北京：中國(guó)建筑工業(yè)出版社，2011.［2］GB 50011—2010 建筑抗震設(shè)計(jì)規(guī)范［S］. 北京：中國(guó)建筑工業(yè)出版社，2010.［3］中國(guó)建筑科學(xué)研究院PKPM CAD工程部. 多層或高層建筑結(jié)構(gòu)空間有限元分析與設(shè)計(jì)軟件(墻元模型)SATWE(2010版)［M］. 2011.［4］CECS 230:2008高層建筑鋼混凝土混合結(jié)構(gòu)設(shè)計(jì)規(guī)程［S］.北京：中國(guó)計(jì)劃出版社，2008.
